Practice Exams Flashcards
Which component encrypts the virtual machine files?
Data Encryption Key (DEK)
For a powered off VM, how much additional free space on the datastore is required to delete a snapshot, committing the snapshot delta disk to the base disk?
0 GB
If you are repointing a vCenter Server to an existing domain, in which scenario would you need to run a precheck and why?
Multiple vCenter Servers exist in the source domain.
Details: If the source domain contains multiple linked vCenter Servers, the repointing process involves additional steps to shut down the vCenter Server and unregister it from the source domain.
You are creating a resource pool in a DRS cluster. Which state is FALSE?
- To specify a limit, select the Unlimited check box.
- When you create a child resource pool, the system applies admission control.
- The default CPU reservation is 0.
- The default memory limit is 0.
- If you choose Scale Descendant’s Shares, child pools use scalable share.
To specify a limit, select the Unlimited check box.
A shared cache server appears to be suffering from storage congestion. Storage I/O Control is already enabled on all company datastores. Which two steps can you take to improve the performance of the cache server?
- Configure storage shares per VM.
- Configure storage limits per VM.
What are valid settings for Define Host Failover Capacity when configuring a vSphere HA cluster?
- Dedicated Failover Hosts.
- Slot Policy (powered-on VMs).
- Cluster Resource Percentage.
What’s the maximum percentage of bandwidth that can be reserved on a physical adapter using Network I/O Control (NOIC)?
75% (i.e. 7.5 Gbps of a 10 Gbps adapter).
What product introduced Virtual Hardware Version 20?

ESXi 7.0 U2 (7.0.2)
What product introduced Virtual Hardware Version 18?
ESXi 7.0 U1 (7.0.1)
What product introduced Virtual Hardware Version 17?
ESXi 7.0
What product introduced Virtual Hardware Version 15?
ESXi 6.7 U2
What product introduced Virtual Hardware Version 14?
ESXi 6.7
Virtual Machine Component Protection (VMCP) valid settings in vSphere HA cluster > Failures and Responses:
Datastore with PDL (Permanent Device Loss):
a. Issue Events.
b. Power Off and Restart VMs.
Datastore with APD (All Paths Down):
a. Issue Events.
b. Power Off and Restart VMs - Conservative Restart Policy.
c. Power Off and Restart VMs - Aggressive Restart Policy.
T/F: Datastores that are SIOC (Storage I/O Control) enabled must be managed by a single vCenter Server system.
True
What recommendations can an administrator incorporate to improve vSphere vMotion performance?
- Use at least two port groups.
- Use 10 Gbps Ethernet or above.
An admin is tasked to upgrade vSphere 6.7 to 7.0. What conditions could cause potential conflicts or outages to the VMs?
- Use of third-party vSphere Installation Bundles (VIBs) installed on ESXi hosts.
- The upgrade of a VDS 6.5 can cause a brief interruption of traffic (this is not the case if using VDS 6.6 or higher).
while creating a VM in vSphere 7.0, you want the virtual disk AND NVDIMM devices to share the same PMem resources. Which option is used?
In the Storage Type settings, select PMem. If you chose this option for a VM, its default virtual disk, new virtual disk, and NVDIMM devices share the same PMem resources.
T/F: During vSphere 7.0 upgrades, VMFS3 is automatically upgraded to VMFS5.
True
T/F: During vSphere upgrades, VMFS5 cannot be upgraded to VMFS6. You must create a VMFS6 datastore and migrate VMs to it.
True
An administrator wants to be able to send vCenter Server log files to a remote syslog server and analyze logs using vRealize Log Insight. What step must the admin take to meet this requirement?
Configure log file forwarding using the vCenter Server Management Interface.
You want to change the logging for the VMware Tools installation so that vminst.log is sent to the host, but vmmsi.log remains in the VM. What option is used?
Vmx.log.guest.level = “info”
An administrator is unable to manage certificates with the vSphere Client. What is another supported option that can be used to manage certificates?
Command Line Interface.
What is the value %DRPTX for when using ESXTOP?
The percentage of transmit packets dropped. It indicates that the physical network adapter cannot meet the demand, perhaps due to load from other VMs.
